CONDUCTIVE ROD LEVEL SENSORS
PRODUCT OVERVIEW

WHAT ARE ROD LEVEL SENSORS WHY CHOOSE ROD LEVEL
AND CONTROLLERS? SENSORS AND CONTROLLERS?

TURCK liquid level probes may be ■ Adjustable sensitivity
used in conjunction with TURCK level ■ Single set-points
control monitors, to provide a simple ■ Multiple inputs
solution for liquid level applications. ■ On/off delay
The resistance between the terminals is ■ Programmable outputs
measured to determine the level of the
medium in the tank. WHERE CAN I USE ROD LEVEL
SENSORS AND CONTROLLERS?
TURCK also offers stainless steel probes
and stainless steel holders with ceramic ■ To control the filling and draining of a

provide single-point level control, tank, or as high and low level alarms.
while the holders are sealed to

of liquids, as well as distinguishing
between liquid and foam.

■ To set an adjustable on and

off-delay for use in turbulent
liquid level applications.

■ To control overflow monitoring.

Level Detection Application Examples MAX Time
MIN On On Off Off On
Control for Pump-in
“Filling” a Tank Example Application using MK91-12-R/...

The MK91-12-R will start a pump or
open a fill valve when the liquid drops
below the MIN level probe and will
remain on until the MAX level probe is
reached. The relay then de-energizes
and stays off until the MIN level is
reached. The pump or valve does not
cycle constantly, as would be the case if
only one sensor were used.
